A19 supports MTE: https://news.ycombinator.com/item?id=45186265 https://news.ycombinator.com/item?id=45186265
Which is a very powerful feature for anyone who likes security or finding bugs in their code. Or other people's code. Even if you didn't really want to find them.

- philodeon 1y agoMIE is a combination of enhanced MTE (EMTE) and some highly-overdue software allocator improvements.
- tucnak 1y agoIt certainly took them a while to introduce MTE! Pixel 8 came out in 2023. I wonder how it compares against hardened_malloc with 48-bit address space and 33-bit ASLR in Graphene. Apple's security team has reported that MIE could break all "known" exploit chains, but so does hardened_malloc. Hard to tell right now which one is best (most def MIE) but everything else included in Graphene is probably making the point moot anyway.
- rising-sky 1y agoYes, but it is not MTE, they are technically different. That's what I was attempting to point out but thought it may have been a typo
